Frequency comb ptychoscopy [PDF]

Nature Communications, 2021
Multiheterodyne techniques using frequency combs—radiation sources whose lines are perfectly evenly-spaced—have revolutionized science. By beating sources with the many lines of a comb, their spectra are recovered.

Wavemeter calibration by frequency comb. [PDF]

Metrologia
Abstract Upgrades to the vacuum wavelength calibration service at the National Institute of Standards and Technology are reported. The instrumentation centerpiece is an optical frequency comb stabilized to a GPS-disciplined oscillator, thereby providing direct traceability to the SI second. Historically, the service has covered lasers at

Frequency-modulated comb LIDAR [PDF]

APL Photonics, 2019
Frequency-modulated continuous-wave LIDAR (FMCW LIDAR) has been widely used for both scientific and industrial tools. Here, in this report, a new class of LIDAR technique based on an optical frequency comb, named frequency-modulated comb LIDAR (FMcomb ...

XUV FREQUENCY COMB SPECTROSCOPY [PDF]

Laser Spectroscopy, 2010
We report the first demonstration of frequency comb metrology at extreme ultraviolet wavelengths (XUV), based on parametric amplification and high-harmonic generation of frequency comb pulses, which results in an 8-fold improved helium ionization potential.

Optical Frequency Comb Generation based on Erbium Fiber Lasers

Nanophotonics, 2016
Optical frequency combs have revolutionized optical frequency metrology and are being actively investigated in a number of applications outside of pure optical frequency metrology. For reasons of cost, robustness, performance, and flexibility, the erbium

Metrology of frequency comb sources: assessing the coherence, from multimode to mode-locked operation [PDF]

Nanophotonics
Since the beginning of this millennium, frequency comb generators have reshaped frequency metrology and related areas. After more than two decades since their first realization, several other ways to generate frequency combs, in any spectral region, have
